Seller's Description

2nd Price Drop 9/22 to $24,950! INTREPID: Designed by Bill King, the Ericson Independence is a masthead sloop, traditionally styled with teak accents, bronze fittings, and with a distinctive trailboard ornamentation on her clipper bow, she gives a nod to America’s historic schooner ships. A deep cockpit and crescent-shaped captain’s bench keep the helmsman safe and snug behind her wheel. Self-steering AUTOPILOT makes short-handed sailing a breeze. New cockpit cushions, covered in a long-wearing Sunbrella textured fabric. The bimini and dodger provide excellent shade. Davits at the stern make for out-of-the way dinghy transport. Below deck, the main cabin is cool and comfortable with CENTRAL AIR, thick, newly upholstered saloon cushions, lots of beautiful wood; An L-shaped galley with sink, front loading refrigerator and 2-burner stove; fold-down chart table, nav station, fold-up wood saloon table, and a quarter berth. The Vee berth sleeps two comfortably and provides ample room for gear and clothing with a hanging locker, drawers, and clever detachable storage pockets. The private head has a new sink, storage cabinet, new solid-surface counters, and a new composting toilet. Built in 1977, INTREPID has been well-kept, upgraded, and newly re-powered with ONLY 168 HOURS on the M3-20B Universal diesel engine. With her 4’11” draft, 10’5” beam, long fin keel, and transom-hung rudder, she is a capable cruiser that will handle well in in rivers and on the bay. From Cruising World review: “This is a stiff and well-balanced boat; it tracks well and is quick to tack;” Contact Urbana Yacht Brokerage for more photos and info. Urbannayachtbrokerage@gmail.com.

Calculations

Hull Speed
6.4 kn
Classic: 6.55 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

6.41 knots
Classic formula: 6.55 knots
Sail Area/Displacement
14.4
<16: under powered

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
14.44
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
39.5
<40: less stiff, less powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

39.47
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
372.0
>350: ultraheavy

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
371.98
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
29.6
20-30: coastal cruiser

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
29.56
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.9
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.85
<2: better suited for ocean passages
>2: better suited for coastal cruising
